Hi, I am a 44 year old female going through perimenopausal symptoms. I am experiencing night sweats, but most concerning is the massive amount of hair I am losing. I have lost so much....that I am becoming very concerned. A PA told me to use women s rogaine, but that isn t stopping the hair falling out and how thin my hair is becoming. My OB/GYN told me that my thyroid was within normal range. She put my on low dose bc pills, but within three months my blood pressure went up. Can a change in hormones cause this much hair to fall out? What do you recommend I do?
